Be'it known that We,-E DWARD.B.HESS and city and State of New York, havednvented certain new*-and-useful improvements 1n writing Machines of which the following is a specification.

This invention is in-p'art an iinprovernent upon the construction disclosed in United- States application of Edward B. Hess; filed August 27,-1901', Seri al No. 73,460, wherein is claimed a flexing connection associated with a key-lever for actuating the type-bar.-

One object of the present invention is to piovide a proper depthof depression oftheiger pieee and key lever, while preserving a proper delicacy or softness of touch;

-A further object is to provide a yielding or" elastic cushion for the finger-piece-that is brought into eflectiveoperation after the: type-bar has impinged upon the platen. This part of the-invention is=applicable generally to writing-machines, wherein flexing Conner/ tions for operating-the type-bars are employed, as shown herein, and in the patents of Edward-B. Hess, Nos. 679,673 and 679,675,-

dated July 30, 1901,1Hess and Stoughton, No. 679,674, dated July 30, 1901, and Edward-B. Hess, Nol 700,687, dated May 20;

Theinventionalso comprehends a new ar-- rangement or. association ,of type bars and universal-b ar-wherein the latter is actuated by.

the-heei or projection of the type-bar beyond itspivotns hereinafter set forth; and also certain arrangements of the type-bar actuating llnks, an angular arrangementof the rear links or parts of the-flexing :connectibnscombinedin a visible-writing machine with a sta+ tionary type-bar segment and shifting platen,

J Fig.- 12; shows a flexing connection operated-by a file will be-tlnownupwardly and forwardlypiece, and from the key-lever a link-9 extends to the joint between 5 and 6. The links 5 6 might be disposed substantially in a horizon- .tal line; but that would require an increased depression of the key-lever or perhaps an undesirable shortness of the front link 6. For this reason the link 6 is inclined downwardly,

as shown. -If,now, the link9 should extend:

ment of the type-bar may be effected and the i necessary softness of touch of the key-lever preserved. The initial movement of the finger-piece or key-lever will oppose less reformed with two loops or eyes, with. which.

sistance to the finger of the operator wnen the link 9 is disposed at right angles, or substantially so, to the link- 6, and therefore we prefer that these two members should nornally stand ninetydegrees apart or at least at an angle not materially greater than that. The angle may be somewhat less, as shown in 'Figfil. If the angle of the link 9 to the horizontal plane of the machine be fort'y-five degree-. t will be found. that the link 6 may be disp...- ed at an angle suitable to effect the relllH l movement of the type-bar, while the desired character of touch may be preser. ed. We prefer the arrangement shown in Figs. 1, 3, and 4, where the links 6 and 9 are ninety degrees apart and are-respectively. at an angle of forty-five degrees to the horizontal plane of the machine. This will atl'ord a finger-piece depression of about one-half an inch, which is standard. hen the links 6 and 9 are disposed generally in the relation suggested, the type-her is started into action under favorable conditions, and the increase? of the angle between 5 and 6 on the further not such as to cause a noticeable or practicallyobjectionable increase in hardness. of the touch. In the arrangement shown the link 5 is separated from the links 6 and 9'by substantially equal angles, and all .three links are subjected to tensile strain only. The end of one of the links 5 6 (the lattcr one being so shown in Fig. 1) is bent into 8 shape or is eyesat the ends of the links 5 and 9, respectively, engage. In Fig. 3 the end of the link 0 s bent back upon itself, then across, and

finally back again to form loops or eyes 10,

with which eyes on the ends of the links 5 and 6 engage. In Figs. 4 and 5 the ends of the links 5,6, and Q are united by a. couplingtrated in Figs. 6 to 12.

plate 11, having triangularly-disposed about a central point or aperture 12 three posts or bosses 13, over which loosely slip the eyes at the ends of the links, which are retained in position by a guard or headed bolt 14, screwing into the central aperture 12. The under face 15 of the bolt-head isinclined, as shown, to allow twisting or play of the eyes at the ends of the links to relieve torsional strain, particularly of those links that actuate the end type-bars of the machine.

The second part of thisinvention'is illus- In Fig. 6 the link 6 is a coiled spring adapted to swing freely about point 7 and of such stifiness as not to yield materially, if at all, during the excursion of the type-bar to the printing-point but thereafter it will yield and so cushion thefingerpiece at the bottom of the its stroke. Fig. 7 shows the finger-piece and key-lever depressed sul'liciently to bring the type-bar against the platen, and Fig. 8 shows a further depression under the stress of which the spring-link 6 is extended. This construction gives a soft cushion touch to the finger-piece, the advantage of which is well understood. Any one or all of the three links 5 6 9 may be .in whole or in part a spring. In Fig. 9 the link 9 is shown as a spring. in Fig. 16 links 6 and 9 are springs. In ,Fig. ll link 5 is a spring.

The arrangement of links in Figs. 6, 7, S. 10, and 11 is the same as in Figs. 1 to 4, and, as

has already/been described, with the mere addition to the structure of the spring feature for cushioning the finger-piece at the bottom or lowcr part of its stroke. Li Fig. 1'2 the flexing connection composed of the links 5 6 is actuated by a finger-piece .r'above it and appropriately connected thereto, as by. the stem 3 It is not contemplated that the spring link ornicinbcr shall serve to return the type-bar from the platen.

cushion etlcct described iould' be oneof the links in whole or in part. since the fixed piece or point to which the front link is attached may yield. For instanceyin Figs; 6 to 12 the part marked .2, which is to 'be appro-' may itself be a spring ofsuch capacity as to atlord the desired cushion ctl'ect.

Hess.

This invention is limited to certain special subjects-matter disclosed in the specification and claims.

Referring to Figs l l4, and 15, it will be observed that the various ke' v'-levcrs 8 are pivoted at 20 toward the rear of the machine a convenient and one,

The line in which the apert ires. 22 lie might be a straight transverse one; but some reasons that it'be be turned toward the. platen. Various keylevers 8 are arranged at the rear as closely togetheras is desirable and diverge toward the front of the machine we transverse r ine located in front of the series of apertures 22.

EGOtiODS between the key-levers and typears; Y

To afford a-uniform depth of depression of the various finger-pieces, the front links 6 of the flexing connections corresponding with and connected to the longer key-levers may be made shorter than the links 6 in the connections corresponding with the shorter keylever. This is illustrated in Eigs.'14 and 15, whichshow, res e'ctively, one of the shortest The intermediate key-levers of two different lengths will be connected with flexing connections having front links 6 ofpro ortionate A spring 25 may be app ied to the heel 'or projection 26 of each type-bar. The type-bars are to be mounted in the usual segment, which, however, is omitted from the drawings for the sake of clearnessQ The ordinary pivot rod or wire upon which the various type-bars may be mounted to rock is shown in Figs. 14 and Hand other figures, being. marked 27. It is ofcourse-of segmental contour, corresponding f with the curve of the segment but it is only shown in .section. Beneath the pivots of the typebars is mounted a universal bar 28, which is curved to conform to the curve in which the links 6 of the various flexing connec the printing-point.

.blow or impact of lateral strain of .the con-- ward by impact of respective type-barpivots lie and is supported by three vertical links, one, 29, at

30, in the middle, and all of whichare attached to a rock-shaft 31, that may be appropriately mounted in bear-. ings in the sides of the frame. A'spring32 each end, and another,

applied to this universal bar may be atthe arm or link 30, as in Figs. 14

tached to and 15. The projections .or heels 26 of the several type-bars are so shaped or are formed. ..with an extended part 33 that they strike bar 28 when thrown to The type-bar, which is weighted more or less at its outer or free end by the type-carrying head, moves freely under thestress of the flexing connection through the greater part of its excursion toward the printing-point and ac uires a con against the universal siderable momentum.- While t us moving, the heel of the type-bar or the part 33 there of strikes the universal'bar and forces it forward, as indicated by-the dotted line. The

universal bar is delivered with hammer-like effect and the universal bar is moved without impairing, tent, the impact of the type upon the platen. With the general form of type-bar-actuating device herein illustrated there is a rise in the velocity .of the type-bar from its initial movement platen, and the rise in velocity is most rapid during the latter part ofthe excursion of the type-bar. This fact makes particularly advantageous the conjoint use of such typebar-actuating devicesand a universal bar actuated as described; Asthe universal bar is belowthe type-bar pivots and is thrown forthe type-bar heels, not only is the momentum of the type-barsused to most advantage, but the movement of the universal bar may be transmitted to the devices to be actuated bylight links or devices which are required to resist tensile strain only. Mgreover, with this construction there is no danger of bending the type-bar by reasonpf the repeated impacts against the universal bar, and the point of pull upon the type-bar is on the same side of the type-bar pivot .as the point of impact against the universal bar, and these two oints are comparatively close together. T ese are important practical considerations. character of the blow of the part 33 upon the universal bar 28 the spring 32, applied as shown or elsewhere, may be a comparatively at least to a disadvantageous ex until it impinges against the the part 33 against the IIS Owing to the stiff one and of considerably greater strength move andhold the type-bar away from the vated by means type-bars.

rear links, combined with platen immediately after the moment of the impact, and thus prevent vibration of the type upon the platen-surface.

The universal bar may be connected to the carriage and ribbon devices in any suitable or well-known way.

The frontends of the front links 6 in the special line, or substantially so, and are in the same .horizontal'plane, or substantially so. This line is preferably located above a horizontal plane midway between like planes bounding the bottom and upper ends of the curved series of type-bar pivots or the curve in which the bars lie. The rear ends of the front links 6, which extend downwardly, will be approximately in said midway horizontal plane, and the rear links will extend therefrom in varying angular directions to their. respective This is When the machine is constructed with front links 6 of different lengths to afford uniform depth of depression of the finger-pieces, their rear ends will or need not lie in one horizontal line, but nevertheless the rear links 5 will be disposed at varying angles substantially as stated. If the rear ends of front links of varying length are arranged in the same horizontal plane, then either the angle of the links must be varied or their front ends must be disposed in varying hori zontal planes. This general disposition of-the a fixed type-bar support and a shifting platen, constitutes a feature of the present invention and is distinguished from a construction, such as shown in the application of Edward B. Hess, Serial .\'o. 57,588, filed April 26, 1901, where in the front fixed ointof each flexing connection is in line iiorizontally substantially with the pointof attachment to its type-bar and a shifting segment and stationary platen are employed.

Any suitable shifting-platen organization may be adopted. convenient and practical construction, but forms no part of this invention, being shown in an application of Edward B. Hess, Serial No. 73,570, filed August 28, 1901. The platen is mounted on-the carriage 51, having an appropriate number of grooved lugs 52, that embrace and travel upon the upper and lower edges of a Hat plate mounted in elongated vertical brackets 54, having rearwardly-extending lugs embracing and sliding upon vertical posts 55, suitably mounted in the frame. The lower position of the platen is determined by collars 56 on these posts. The brackets 54 and the cross plate or bar 57, connecting them at the bottom, constitute a frame which may be elefrom the end of which at the left construction shown are arranged in a .smgle transverse I points of connec' 'tion between the rear links 5 and type-' indicated in Fig. 16;

That shown in Fig. .16 is a.

or track 53,

of one or more arms 58, ex-

mounted in the side plates of the frame, and side of the machine rojects forwardly an arm 60 A strap or link 61 connects this arm with a shift key or lever 62, having a fingeriece 62- applied to itsu of the machine. here may be one arm 58 at each side of the machine. The mode of operation is obvious and further description seems unnecessary.

Figs. 17 and 18 show'an arrangement bv which a uniform depth front links 6 of uniform length. This is ac; complished by carrying the connection of the link 9 forward or toward the front end of the key-lever, asshown by Fig. 17 in comparison with Fig. 18.

Figs. 19 -and 20" show a new forin'of typebar spring by which a perfectly straight and symmetrical disposition of the strain and pull upon. the type bar is obtained. coiled part 63- of the spring is a common construction. The end of the wire is formed into a loop 64, .a'nd'its free end, which is hookshaped, engages one or more of the convolutions of the spring, preferably at a point diametrically opposite the point from which the wire and extends from the convolutions for the formation of the loop. The end of the loop which occupies the aperture in the ty ebar heel or projection'is contracted and is of depression of the finger-pieces is obtained while employing The tending rcarwardly from a rock-shaft 59, 65

turned ends at the ront.

preferably only of sufiicient width to give a proper bearing without unnecessary friction in the aperture in the type-bar. When thetype-bar moves to the printing-point, its heel or projection passes into or through the stirrup or loop 64. This construction affords an even or unifornistrain on the type-bar and operates to reduce or entirely overcome torsion and friction with the end bars. This,

style of spring may be 'applied in all the modifications shown in the various figures in lieu of the ordinary s ringstherein shown and marked 4. This I projection of the type-bar with the spring, since in all cases the projection must pass into and throu 'h theloop without possibility of collision with-the sides thereof.

In the organization exception of that shown in Fig. 9. allthree of the angularly-disposed links 5. 6 '9 are subjected to'tensile strain only. A furthe'r'feature of the construction is the employmentof universal joints in the following places,which are named in the order oftheir importance in the practical construction and operation of oop construction obviates any danger of collision of the heel orillustrate'cl, with the I the writing nachine: that between the links 5 6, between the link 5 and type-bar, between the link 9 .andthe links 5 6, between the link 9 and the key-lever 8 and between the link 6and its fixed point orsupport7.
